Migrating data to a different storage system – HP XP Array Manager Software User Manual

1.
In the Resources or Mobility tab, select a migration source host or logical group. From a list of
hosts or logical groups, you may also select migration source volumes. If migrating data from a
mainframe volume, expand the Tiers tree on the Resources tab or the Mobility tab, and then select
the corresponding tier.
2.
Click the Migrate Data button.
3.
Verify that the correct migration source volumes are selected, and then click Next.
4.
Specify the migration target, THP/Smart pool or tier and then click Next. When the parity group
selection rule is set, a candidate volume that is appropriate as a migration target is selected
depending on the application that is being used or the usage rate of the parity group. Specifically,
the system attempts one of the following:
• Balance Capacity: Selects a migration target candidate so that the remaining capacity of the
targeted parity group is equalized with other parity groups.
• Maximum Coverage: Selects a candidate for the migration target from as many parity groups
as possible.
• Minimum Coverage: Selects a candidate for the migration target from as few parity groups
as possible.
5.
Confirm that all migration source volumes and target volumes or THP/Smart pools are paired
properly, confirm that no other problems exist, and then click Next. If necessary, change the
pairs. To change a pair, first select the volume pair, then from the Other Candidates for Migration
list, select the target volume to change to, and then click Map Volume.
6.
Specify plan options as necessary, and then run the task.
7.
In the tasks list, confirm the result of the task. After a task is created, you must not perform any
operations on volumes included in the task by using HP StorageWorks P9000 Command View
Advanced Edition Suite or other programs until the task has finished executing.
